(8) Calculation Initial setting of
R/G/B_HIGH
(9) Set Initial setting of
R/G/B_HIGH
(10) Original WB adjustment is performed (HIGH)
Set the specified gradation for point 2, fix the
most faint colour to get reference value,
adjust others 2 colours to minus adjustment
for reference value of point 2.
(11) Measurement HIGH Brightness
(Set) R_HIGH= G_HIGH
G_HIGH= G_HIGH
B_HIGH= G_HIGH
(12) Calculation MAX luminance after WB
ADJ set to γ=2.2 (LXHG)
(13) Set R/G/B_MAX
(14) Calculation LOW luminance (γ=2.2)
(15) Calculation Initial setting of
R/G/B_LOW
(16) Set Initial setting of R/G/B_LOW
(17) Original WB adjustment is performed (LOW).
Adjust RB to the reference value of point 1.
(18) Adjusted value is writing at [command]

(19) Calculate the slope R2
slope,
G2
slope,
B2
slope
between MAX and Point2.
R2
slope =
(R

- R
high
)/(4080-3664)
(20) Calculate the correction value
⊿R
high,
⊿G
high,
⊿B
high.
⊿R
high =
R2
slope X
(3840-3664)
(21) Set the reference value R,G,B of point 2
(R2’)=R2+⊿R
high
(22) Calculate the slope R1
slope,
G1
slope,
B1
slope
between Point2 and Point1.
R1
slope =
(R
high
- R
low
)/(3664-640)
(23) Calculate the correction value ⊿R
low,
⊿G
low,
⊿B
low.
⊿R
low =
R1
slope X
(717-640)
(24) Set the reference value R,G,B of point 1
(R1’)=R1+⊿R
low
(25) Shut down the AC power.
